Number grid formulars. algebra.

I was wondering if anyone could be able to tell me the algebra formulars for the number grid.

i know that windows sized 2*2 is --number=n--

(n+1)(n+10)-n(n+11)
=10.

can somebody please tell me the rest from 3*3 up to 7*7. i would be very gratefull, i is because i am in year 10 but our teacher wants us to take our GCSE's in november and this coursework has to be handed in next monday.

thank you
